I would suggest that you do a lot of research on opiates before you accept advice on Internet forums. I have heard a lot of scare tactics, but realistically you become dependent on them for your pain relief, not addicted. Addiction is a psychological response, when you crave them for emotional reasons. Pain relief is a legitimate usage, unlikely to result in true addiction, and opiates have few side effects compared to many other drugs.

That said you want to try anti-seizure meds and always take as low a dosage as possible to achieve functionality, not total pain relief. That is too much.
